Which of the following oil filter designs is used in modern diesel engines?

Modern diesel engines utilize a variety of oil filter designs to ensure optimal engine performance and longevity, which is why the choice indicating all of the options is the most accurate.

Surface type filters are designed to capture particles on the filter's surface, providing a quick approach to filtering larger debris. Depth type filters, on the other hand, trap contaminants throughout the filter media’s thickness, which allows for the retention of smaller particles over a longer time span.

Combination type filters incorporate features of both surface and depth filters to maximize efficiency and filtration capabilities. This versatility in filter designs caters to the different demands placed on modern diesel engines, such as the need for extended oil change intervals and the management of increasingly stringent emissions standards.

By using a combination of these filter types, modern diesel engines are able to maintain better oil cleanliness and performance, emphasizing the importance of having all these designs in contemporary automotive engineering practices.
